WILLIAM G.- FARNUM, or ARLINGTON, VERMONT, issmmme -WYCKOFF, SEAMANS &BENEDICT, or ILION. NEW YORK-,A'CQRL i PORATION OF NEW YORK.

Be it known that I, WILLIAM C: FARNUM, a citizen of the United States,and a resident of'Arlington, in the county of Bennington and State ofVermont, have invented certain new and useful Improvements inType-Writing Machines, of which thefollowing is a specification.

More particularly my invention relates. to printing point and lineindicators for typewriti "machines, and'has for its object to provi eimproved means of the character specified.

Tothis end the invention consists in certain features of construction,arrangements of parts, and combinations of devices, as hereinafter setforth, and pointeclout in the appended claims.

v In the accompanying drawings, Figure 1 is typewriting machine raisedto expose the printin -point with part of the rear bearingrod an showingmy invention in operating 'riage intermediate the Fig.2 and that shownin ig. 4, in which lat-. 3,

Fig. 3is a view similar to Fig.2, but with the carosition shown in ter viewthe carria e is shown as lowered and ready to print. ig. 5 is afragmentary view of the upper part of the indicator. Fig. 6 is avertical .front-to-rear sectional view of a type-writing machineembodying my invention.

In the several views, in which like parts are designated by likenumerals of reference throughout, portions of the machine are omitted orbroken away in order to disclose the invention more clearly.

Coming now more particularly to 'the -g mechanism proper of myinve1'1tion,: 25 r isyan I indicator orpointer pivoted orhinged at 26 tor:

a bracket 27, screwed or otherwise attached to any convenient fixed partof the upper'f portion of the machine, at the rear thereof and at ornear the center. I have shown the in-:.;' dicator as having thetwo sidepieces 28 28:

bent near their upper ends and-joined: at the top by the cross-piece 29,andthis is the form I prefer as best.combining'lightness and stability;but it will be understood 131131911 do not limit myself to theconstructionshown':

Attached to the rear carriagerod-Sat or near its ends are two brackets30, only%thefi left-hand one of which is shown',-"and sup ported therebyis the light-rod 31 Whichrun's 5 i substantially the length"of1-the"-platerr.-j

Loosely embracing the ;rod 31 "at 32 is the-- connecting link or piece33, which is hin ed or pivoted to the-pointer251M 34. The'dhu- 5:ble-acting spring 35, which, "with the 'link-33 controls the pointerorindic'atorf-25 which ,is =l 1ere shown in'the-fornr of 'wire, is pivotedat 36 tothe; supporting bracket 27 and at 37 to the indicator or pointeron a slight ollset thereof, the pivot 257 being slightly to the rear ofthe pivot or hinge 26, which connects the indicator or pointer 25 to thebracket 27. The cross-- piece 29 carries the indicating devices proper,which consist ol line and letter indicators for both upper and lowercase, aswell as an indicater for the platen-scale 18.

Referring to Figs. 1 and 5, the lower-caseletter indicator is denoted by38 and the corresponding lineiiidicator by 39. 40 denotes theupper-case-letter indicator, and. 41 the line-indicator. 42 denotes theplaten-scale indicator, which serves for both positions otthe platen.'llLe dlil'erence of position 'of the pointer 25 as to the line ofwriting is represented by the distance between the line-indicators 39and 4-1 on the pointer 25 and is due to the change of relation betweenthe fixed pivot 26 and the rod 31, controlling the pointer 25 when thepl:ttOIlflJLll'lUl by which. the rod 3] is carried is shifted to changecase.

The operation of my invention will now be described. Referring to Fig.4, the platen is seen in printing position. with the pointer 25inoperative and ing contiguous to the ribbo=n-plate 22. The pointer 25is held in this position by gravity, as well as by the action ofspring35 pressing at pivot 37, which in this position of the pointcr25is above an imagi nary line connecting pointer-hinge 26 with pivot 36.It will of course be understood that whatever be the position of theplaten, longitudinally considered, in respect of the/ printing-point thepointer or indicator 2:") willalways be under control through its link33, embracing the rod 3], carried by the platen-carriage. Suppose nowthat at any point of its travel in the printing direction theplaten-carrier be swung about the hinges at 10 by the lift-piece'23 forthe purpose of exposing the printing-point until it reaches that pointin its upward travel-shown in Fig. 3. The pointer 25 has been moved tothe )osi'tion shown in Fig. 3 by the connectinglink 33 and rod 31. Thespring 35 has up to this point tended to assist gravity in keeping thepointer 25 as far from the platen 6 as 'the link 33 and rod 81 willpermit. Just here, however, as pivot37 alines with pivots 26 and 36 the)ressure of spring 35 is nullified, being exerte simply to press thepointer 25 against its pivot 26 away from pivot 37. A slight additionalmovement of the platen-carrier in the upward,direction by means oflingerpiece 23 will bring pivot 37 below the imaginary line connectingpivots 26 and 36, and thereupon the action of the spring 35 will bereversed and the pointer 25 will be forced thereby into close proximityto the platen, as shown by the dotted lines in Fig. 3. \Vhen the end ofthe upward swing of the platen is reached, the pointer 25 is in theposition pointer 25 away from the platen.

anisin. has a double action, tending at one stage of.

, other stage toward the platen.

shown in Fig. 2, the slight additional are of movement of the rod 31 inthe platen-twine permitting thespring 3!) to force pointer 25 intosubstantial contact with. t along the line of the cross-piece 2-9. Theiii- .dicator proper will now be in the relation to the printing pointand line as depicted in Fig. 5, the upper-case-letter indicator 40 (hereshown. as graved or cut into the crosspiece 29) indicating theprinting-point, and the upper-case lineindicator 41,. which in itspresent town is a line giaved or cut into the metal of cross,- iiece 2),indicating the printing-line, and the pointer 42 indicating thecorresponding )rinting-point on the letterscale 18. Had

its sliil t-rail 14 been s ii'fted to its forwardv or lower-caseposition before being turned up to ie platen the platen-earner throughexpose the line ol writing, the indicator would appear in relationthereto as shown in Fig. l, the lower-case-letter indicator (in' itspresent form shown as a notch 38 in the cross- )iece 29) indicating theprinting-point, and the lower-case line indicator (here shown as theupper edge 39 of crossiece 25)) indicating the printing-line, 42 ill(ieating the printingpoint on the platen-scale, as before.

In returning the platen-cari'ier with its platen 6 to printing positionthe reverse oi the operation above set forth will take place, thedouble-acting spring 35 holding the pointer 25 in close proximity tothe. plateir or a short distance of the are of return lilOVO- ment anduntil pivot 37crosses lilQlll below to above the imaginary lineconnecting pivots 26 and 36, whereupon spring 35 acts tol orce thusbeseen that pointer 35 is positively re strained from contact with orclose proximity to the platen, except at substantially the moment whenthe pointer 35 is needed to in? dicate the printing point and line.Unnecessary contact with the platen and consequent blurring of the workare therebyavoided, as is likewise any obstruction on theplatenconnected with the paper-feeding or otlier nieehr It will thus be seenthat the spring 35 the swing of theplaten carriei' to force theindicator or pointer 25 away lrom and at anit will l'ur- It will.

therinore be understood that with a shit-tin platen the indicator orpointer serves to indi cate the printing-point and the printing-linewhether the printing istaking place in small or in capital letters-thatis,in lower or upper case. Either of these features may be employed.independently of the other.

While I have illustrated my invention in connection with a Remington No.(3 typewriting machine, it will of course be understood that it may heapplied to any type-' writing machine wherein it may be found availableto employ the essential elements ol I departing .faaare my invention,and, further, that various con-' structional changes may be made withoutfrom the spirit of my invention.
